Multiscale modelling of the mechanical behaviour of oriented semicrystalline polymers

For semicrystalline materials, a stacked lamellar morphology gives rise to a stronglyanisotropic mechanical response. A multiscale numerical model is used to simulate the effect of astacked lamellar microstructure on the macroscopic behaviour. The constitutive properties of thematerial are identified separately for the crystallographic and amorphous domains. The averagedfields of aggregates of individual phases, having different preferential orientations are determined.The anisotropy of preferentially oriented material is investigated in different deformation modes
